Member Function Documentation

Write() [1/2]

template<class W >

bool grpc::internal::WriterInterface< W >::Write ( const W &  msg )

inline

Block to write msg to the stream with default write options. This is thread-safe with respect to ReaderInterface::Read

Parameters

msg	The message to be written to the stream.

Returns

true on success, false when the stream has been closed.

Definition at line 125 of file grpcpp/impl/codegen/sync_stream.h.

Write() [2/2]

template<class W >

virtual bool grpc::internal::WriterInterface< W >::Write ( const W &  msg, grpc::WriteOptions  options  )

pure virtual

Block to write msg to the stream with WriteOptions options. This is thread-safe with respect to ReaderInterface::Read

Parameters

msg	The message to be written to the stream.
options	The WriteOptions affecting the write operation.

Returns

true on success, false when the stream has been closed.

Implemented in grpc::ServerReaderWriter< W, R >, grpc::ServerSplitStreamer< RequestType, ResponseType >, and grpc::ServerUnaryStreamer< RequestType, ResponseType >.

WriteLast()

template<class W >

void grpc::internal::WriterInterface< W >::WriteLast ( const W &  msg, grpc::WriteOptions  options  )

inline

Write msg and coalesce it with the writing of trailing metadata, using WriteOptions options.

For client, WriteLast is equivalent of performing Write and WritesDone in a single step. msg and trailing metadata are coalesced and sent on wire by calling this function. For server, WriteLast buffers the msg. The writing of msg is held until the service handler returns, where msg and trailing metadata are coalesced and sent on wire. Note that WriteLast can only buffer msg up to the flow control window size. If msg size is larger than the window size, it will be sent on wire without buffering.

Parameters

[in]	msg	The message to be written to the stream.
[in]	options	The WriteOptions to be used to write this message.
